Working NVFlash that can flash modified GTX970/980 BIOS's

[almighty15]

Who wants it??

And I'll upload it, just flashed my card to 1200Mhz and no certificate mis-match error ( Still trying to figure out how to flash the second card )

Good stuff for those who like to push their cards. Nice one Al

Unplug the first one

Where's this NVFlash from? Do the chaps over on techpowerup know about it? What are you using to edit the bios?

Nice shameless thievery of some-one else's work there btw

Can it edit voltages and power limit?

 

[JamesM]

Power limit yes.

Voltages don't appear to be working according to GPUz however one guy says that upon flashing his card and using a multimeter on it, the volts were 1.3 instead of 1.25

Edit.. slight change to my latest comment, voltages appear to work fine with my MSI card?!

+150 core and it's now boosting to 1605mhz. No GPUz perfcap limit showing enither!

 

[rtho782]

Sorry, I'm way behind the nVidia times, having been AMD for so long...

What do I use to edit 980 BIOS? nbitor doesn't seem to work these days!

I was just about to start performing hardmods to remove the stupid power limit

 

[JamesM]

Kepler Bios editor 1.27v sort of works.

It's, as the name suggests, made for kepler but does appear to work with maxwell too

 

[JamesM]

My card with the power limit raised to 125% and voltage increased, albeit slightly, to 1.275v

 

[almighty15]

Got mine on water but one card runs 20-25c hotter then other so something isn't right!

Needs stripping down and sorting then I'll push the cards.

Got a pic of your tubing setup?

I think it's more of a mounting issue matey to be honest...

 

[rtho782]

Any guide on this kepler bios editor?

I've increased the voltages to 1275, and increased the top and bottom power limit bits loads, but it's not made any difference, GPU still thinks it is at 100% power limit in furmark...

In fact they've both downclocked to 620mhz. Going back to EVGA SC bios.

NVM.

Ok I have applied a 200% Power-limit on the card. testing....

Going HAM

 

[Besty]

Precision X is now showing 200%. Booting up 3dmark....

So it will apply but during 3DMark it seems to be still held at 125% and my GPU downclocks when it hits it.

Work in progress then...

 

[JamesM]

You'll still be limited with volts if GPUz reports PerfCap reasons.

You want GPUz to look like this on the PerfCap. Basically blank

Ok thanks for the tip, I will use GPU-Z to monitor.
